Short Throw Clutch

Sounds crazy, but for a long time (ever since I replaced my master cyclinder) my clutch pedal is about half the distance it should be from the floor. It actualy doesnt even press the little button that indicates the clutch is out. I drove it around and found it to shifts just fine, and I love the minimal effort/travel. If I adjust the pedal/master all the way out, my knee almost hits the steering wheel before the clutch starts to grab.
Im curious if anyone else has their clutch setup like this, any negitive side effefts, and what the heck does that button do that detects the clutch being fully engaged?

The sensor is called a nuetral saftey switch. The car will not turn over unless the clutch is engaged.

When I finally swapped out my master I had a 'instant' clutch. I don't know what the stock spec is for it to be fully enagaged.

I set mine to be fully engaged when I'm 75% down to the floor. If the clutch seems to engage too soon. It's possible that it's already begining to engage all the time(like riding the clutch). Causing the clutch to slip on heavy acceleration. I would imagine it will eat the clutch up real fast.

Looks like you mixed 3 things up here!!! Neutral sensor is inside the trans, and sends a singal when the shifter is in neutral. The other switch you speak of is the clutch DISENGAGED switch, which yes, does have to be depressed to start the car. The switch I speak of is depressed when the clutch pedal is all the way out (aka your foot is off of it) which is why I called it the clutch engaged switch. It hasnt been depressed on my car for more than a year.
The adjustment on the master cylinder prevents the pedal from coming more than half way up. Therefore, the clutch IS fully engaged when I let the pedal out, the sensor just doesnt know it. Im not having any slipping at all, and I've got 30k miles on this clutch so far. If anything, the clutch isnt coming up off the flywheel/pressure plate as much as it should, but its plenty aparently.

Sorry if I came across as condesending, it wasnt my intent. I didnt know about this "clutch engage" switch until last night when I stuck my head down there. This picture may help, the FSM calls it an ASCD cancel switch.

Yes but my pedal doesnt come up more than half way, the screw only allows for 1/3" adjustment, its still almost 2" short. I will have to make a spacer.

So anyone know what the ASCD cancel switch does??

EDIT: Figured it out, its Auto Speed Conrtol Device, aka Cruise Control. I removed my cruise control, so thats why the lack of contact with the switch wasnt causing any problems.

EDIT 2: Although it isnt shown there, Only the US models have that switch that requires you to have that clutch pedal all the way down before the car will start. I guess they think americans are too dumb to check if its in gear (or bother pushing the clutch in for that matter) before they fire their car up!

Do you know how to adjust the pedal? It may look like it's only a (1/3") difference, but a few turns makes a big difference.

Sorry, I was unclear there. I ment the button only has 1/3" adjustment. The pedal can easily be adusted to go all the way out, as I mentioned in my first post, but it simply requires too much movement (IMO). The way I have mine adjusted, I only have to push it 1/3 the distance if it was adjusted "properly". Hence, short throw clutch.

like you figured out ASCD = cruise control and that's a cancel switch if you press the clutch

There is also a switch at the bottom end of the clutch pedal's travel (towards the floor) that has to be depressed to start the car. I think it's called clutch interlock switch or something close to that. If you look in the service manual at the starting system diagrams (in the EL section), you'll see it.

Both the switches can be adjusted as well as the clutch pedal itself.

As long as you're not riding the clutch like goon mentioned, then you should be fine.
